I've been reading on the forums about folks using the Honda cluth plates on the WR's with the z-start clutch. 1. Has anyone out there had success with the OEM plates, or should I buy Honda plates straight away? 2. There are 9 friction plates in the Yami clutch. Do you replace all of them with Honda plates or just the middle 7 that are the same part numbers. 3. Is the Honda part number for a 2002 WR, PN# 22201-KRN-670? By the way, I have the 290 kit on my WR250F. And I only do trail riding/Harescrambles. I think that's it for now.
